COIN-CONTROLLED YENDING MACHINE.

Application med .Tune 15',

To all whom '5 may can rem.'

Be it known that I, JOHN F. IVATLING, a` citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinols, have invented certain new and useful Improvements in aCoin- Controlled Vending Machine; and I hereby declare that thevfollowing'v is a full, clear,v and exact description of the same,reference being had to the accompan ing drawings, and to the numerals ofre erence marked thereon, which form a part of this specification.

This invention relates to a coin controlled vending machine, and it isamong the objects of this invention to provide a machine in which a coinis periodically returned to the purchaser together with an article thatthe machine is vending so that one articleduring a certain cycle ofoperation may be free to the purchaser. l

The invention comprises the novel mechanism and combinations hereinafterdescribed and more particularly pointed out and defined in the appendedclaims.

In the accompanying drawings which illustrate a preferred embodiment ofthis invention and in which similar reference numerals refer to similarfeatures in the different views:

Figure 1 is a front elevational view of a vendmg machine embodying thisinvention.

Figure 2 is a section on the line 2 2 of Figure 1.

Figure 3 is an enlarged fragmentary sectional view showing the operatingmechanism in elevation.

Figure 4 is an enlarged section taken substantially upon the line 4-4 ofFigure 3.

Figure 5 is a rear elevational view of the vending machine with the backplate removed. a

Figure 6 is a side elevational view of the vending machine.

Figure 7 is an enlarged sectional view upon the line 7-7 of Figure 3.

Figure 8 is an enlarged sectional view upon the line 8,-8 of Figure 3.

As shown on the drawings:

In referring to the drawings there is illustrated the usual casing 1containing in the present instance three vertically extendingcompartments for containing the articles to be ven'ded which may consistof confectionery or the like. The lower ends of these compartments areopen so that the ar- 1923. Serial No. 645,529..v

ticles may drop therethrough by gravity. Adjacent the lower open end ofeach compartment is a pair of disks 2 (Figures 2 and 5). Each pair ofdisks has a plurality of relatively deep notches for receiving thearticle to be vended. The notches of each pair of disks are inalignment, Vbut the notches in the pairs are staggered. In the presentinstance, each pair of disks has three sets of notches so that a thirdvof a revolution of the disks which is the extent of each operation willalways bring a set of aligned notches in position under a compartment.The disks 2 are securad in spaced relation upon a shaft 3 suitablysupported in the casing.

A coin controlled actuator is loosely mounted upon the shaft 3 forimparting a third of a revolution to the shaft 3 upon each actuationthrough mechanism kto be later described. The actuator is best shown inFigures 3 and 4 and comprises a disk 4 having a lateral impellingabutment 5 which is shown as consisting of a short laterally extendingcicumferential flange having a circumferential extent equal tosubstantially one third of the circumference of the disk.

The coins are adapted to be inserted in one of the' slots 6 shown inFigure 1 and drop down through a coin chute 7 shown in Figure 8 andlodge in a concave notch 8 formed in the periphery of a disk 9 securedupon the shaft 3. In the present instance, three spaced concave notchesare shown in the periphery of the disk 9 which is actuated one third ofa revolution so that one coin notch 'properly centering the coin disk 9so t at -it will be in a position to receive a coin.

The actuating disk 4 is provided with a radial shank 11 (Figure 4) fromwhich an operating handle 12 projects. The handle projects t'hrough anarcuate slot in the side of the casing for manual actuation. Thisarcuate slot is normally closed by a. shield 13 extending radially fromthe actuating disk4 which is always returned to normalposition throughthe spring 14 which is connected at one end to the casing and at itsother end to the shank 11.

In Figure 4 a coin 15 is shown deposited in a coin notch in the disk 9.Now by actuating the disk 4 through the handle 12 the abutting end ofthe ange 5 will strike the coin and cause the disk 9 and shaft 3 torevolve a art of a. revolution whereby an article carried by a pair ofthe disks 2 will be dumped into the delivery chute 16. Upon release ofthe handle 12 the actuator will be drawn back to normal position by thespring 14.

In the present instance, in which three actuations are designed lutionto the shaft 3, one of these actuations will return the coin bydepositing it in the delivery chute 16. The partsare so designed thatevery third actuation will return the coin to the purchaser. This isbrought about as follows:

In Figures 7 and 8 there is shown a swinging arcuate guide 17 pivoted atone end and so positioned with respect to the coin disk 9 that it willnormally guide the coins past the delivery chute 16, the coins ridingover a stationary guide 18 and dropin in the rear of the casing whichconstitutes thecoin box. Mechanism has been provided for swinging theguide 17 outwardly every third actuation of the actuator 4 so that thecoin will drop in the delivery chute 16 with the vended article.

In referring to Figure 7, it will be noted that a three armed block 19is secured upon the shaft 3; two ofthe arms are short and duringrotation of the shaft 3 they will not affect the swinging guide 17; thethird arm, however, is long and is adapted when it comes` around tostrike the guide 17 and swing it outwardl a 'suiiicient extent so thatthe coin will rop from its notch into the delivery chute 16.

A spring pressed arm 20 pivoted at its to impart one revolower end isspring impelled by the spring 21 against the side of one of the arms ofthe device 19 for centering the shaft 3 in its statlonary position.

While the present vending machine is designed to return every third cointo the purchaser, it should be understood that this is for the urpose ofillustrating only. It is contemp ated that any predetermined actuationof the machine may return the coin.

I am aware that nany changes may be made, and numerous details ofconstruction may be varied through a wide range Without departing fromthe principles of this inven tion, and I therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

I claim:

1. In a coin controlled vending machine, a rotatable coin carrying disk,means for rotating the same through the interposition of a coin, aswinging guide for retaining the coins in said disk to discharge intothe coin depository, and an arm connected for rotation with said coindisk and adapted at intervals to swing said guide to allow a coin todrop into the delivery chute-of the machine.

2. In a coin controlled vending machine, a rotatable article ldeliveringdevice, a coin disk secured thereto, an actuator for the disk movableguiding mechanism for retaining the coins on said disk and means forperiodically rendering said guiding mechanism inoperative.

In testimony whereof I have hereunto subscribed my name.

JOHN r. WATLING.
